Reaction Steps

As before in Example 134, a solution of (E,E)-5-(2-methoxyphenyl)-5-(4-methoxyphenyl)-2,4-pentadienoic acid 4-nitrophenyl ester (1.5 g) an 3-pyridinebutanamine (0.64 g) in tetrahydrofuran (15 mL) was stirred overnight at room temperature. After the usual workup, the crude product was crystallized from ethyl acetate to furnish 1.25 g of (E,E)-5-(2-methoxyphenyl)-5-(4-methoxyphenyl)-N-[4-(3-pyridinyl)butyl]-2,4-pentadienamide, mp 164°-165° C.
